Air Pre-heater in Waste Heat Recovery Boiler--

An air pre-heater (APH) is a general term to describe any device designed to heat air before another process (for example, combustion in a waste heat boiler) with the primary objective of increasing the thermal efficiency of the process. There are two types of air pre-heaters for use in steam boilers in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air pre-heater.
